Hexamethylenetetrammonium salts, composed of energetic anions 3,5-dinitropyrazolate, 4,5-dinitroimidazolate, 3,5-dinitro-1,2,4-triazolate, 5-nitrotetrazolate, perchlorate, nitrate and azide, were synthesized and characterized. The structure of N-methyl-hexamethylenetetrammonium 3,5-dinitro-1,2,4-triazolate (6) was confirmed by X-ray analysis. The standard enthalpies of formation for the new salts were calculated
合成并表征了由高能阴离子3,5-二硝基吡唑酸盐、4,5-二硝基咪唑酸盐、3,5-二硝基-1,2,4-三唑酸盐、5-硝基四唑酸盐、高氯酸盐、硝酸盐和叠氮化物组成的六亚甲基四铵盐。N-甲基-六亚甲基四铵 3,5-二硝基-1,2,4-三唑酸盐 (6) 的结构通过 X 射线分析得到证实。新盐的标准生成焓是通过使用计算可行的 DFT(B3LYP) 和 MP2 方法结合基于盐密度的经验方法计算的。计算值范围从 ΔHf° = –30.6 (7) 到 +468.8 kJ·mol–1 (10),其中实验密度 > 1.35 g cm–3。(© Wiley-VCH Verlag GmbH & Co.
